I just don't understand the appeal of reels for the average user posting them (eg, not a "creator"). All comments come through as DMs which feels weird/creepy. The social/engagement is out the window; your friends can't comment on your content and reply to each other. It's just an effing weird one-way broadcast medium that's painful to deal with (might randomly play sound, might show photos for too long/too short, video with no easily usable scrubber, etc). The only "advantage" I see is that it's limited to 24h so you don't feel like you're making as permanent a record of your content. I'm sure some "younger" folks (who are probably 35 now) thought this was a good antidote to the generation before them being embarrassed by their old FB content, but man. I just hate reels.
Thankfully I don't doomscroll or otherwise sucked into the content generated by randos; I mostly only see stuff my friends post, but man, I would pay good money to never have to see a "suggested" anything again.
